This is the PATH
variable without sudo:
$ echo 'echo $PATH' | sh
/opt/local/ruby/bin:/usr/bin:/bin
This is the PATH
variable with sudo:
$ echo 'echo $PATH' | sudo sh
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin
As far as I can tell, sudo
is supposed to leave PATH
untouched. What's going on? How do I change this? (This is on Ubuntu 8.04).
UPDATE: as far as I can see, none of the scripts started as root change PATH
in any way.
From man sudo
:
To prevent command spoofing, sudo
checks “.'' and “'' (both denoting
current directory) last when searching
for a command in the user's PATH (if
one or both are in the PATH). Note,
however, that the actual PATH
environment variable is not modified
and is passed unchanged to the program
that sudo executes.
